Tang is the latest in a long line of developers looking to profit by tearing down a smaller, older home in Seattle and replacing it with a larger and much more expensive one.

Seattle now sees one home teardown per day on average, with the rate of teardowns surging in the last year and a half. The typical new home that springs up on a tear-down lot sells for more than $1 million, about three times more than what its old, torn-down predecessor was worth.
